UFC CEO Dana White has revealed that the organization is working directly with federal investigators after betting concerns surfaced during Isaac Dulgarian’s fight against Yadier Del Valle at UFC Vegas 110.
The issue arose when UFC’s betting integrity partner IC360 noticed “unusual action” on the bout. Dulgarian, initially a strong favorite, saw his odds collapse hours before the fight. Multiple sportsbooks—including Caesars and William Hill—later refunded bets made on him following his first-round submission defeat.
White told TMZ Sports the UFC immediately contacted Dulgarian before the event after being warned of the betting irregularities.
“We called the fighter and his lawyer and said, ‘What’s going on? There’s some weird betting action going on in your fight. Are you injured? Do you owe anybody money? Has anybody approached you?’” White recalled. “The kid said, ‘No, absolutely not. I’m going to kill this guy.’”
When Dulgarian was finished in the opening round by rear-naked choke, White said the UFC’s next call was to law enforcement.
“Literally the first thing we did was call the FBI. I’ve met with them twice today,” he said.

White: “We Will Be Your Worst Enemy”
According to White, the UFC has since met with FBI agents, including director Kash Patel, as the investigation unfolds.
“I talked to him this morning and then we just had an office full of FBI agents in here,” White explained. “If you try to do this, we will be your worst enemy. We’ll come after you with the FBI and whoever else we need to get. We’ll do everything we can to make sure you go to prison.”
Dulgarian has since been released from the promotion.
Investigation Connects to Earlier Fight-Fixing Scandal
White compared the situation to the 2022 Darrick Minner–James Krause investigation, where betting lines shifted before Minner’s 67-second loss to Shayilan Nuerdanbieke. That case, still open, now ties into the current probe.
“That investigation is still ongoing and will now be part of this one too,” White confirmed.
Though careful not to label Dulgarian guilty, White said the signs are worrying.
“I’m not saying this kid’s guilty — there’s no proof yet. But it doesn’t look good,” he said. “We asked him everything — if he was hurt, owed money, or was approached. He said, ‘Absolutely not.’ The fight ends, and I called the FBI right after.”
White Shuts Down “Hundreds of Fights” Rumor
White dismissed social media chatter claiming that dozens or even hundreds of UFC bouts are under federal review.
“People saying there are hundreds of fights being looked at — total bullshit,” he said. “IC360 monitors all betting on every UFC event. There aren’t hundreds of investigations. All clickbait.”
He also addressed fighters who have claimed online that they were offered money to throw fights.
“You’re seeing fighters say, ‘I was approached,’” White noted. “Why didn’t you tell us or the police? That’s really weird. They’re going to be approached now by the FBI.” via MMAFighting
As the investigation continues, the Nevada State Athletic Commission has reportedly withheld Isaac Dulgarian’s fight purse pending the outcome of the review. The UFC maintains that the integrity of the sport—and its fighters’ reputations—remain its top priority.
Dana White is breaking his silence after suspicious betting activity was observed before Isaac Dulgarian, a heavy favorite, lost on Saturday.
